Specification of Letters Patent.

" Patented June 19, 1906.

i To all whom it may concern: 1

doorways; and it consists in the simple, du-

rable, and efiicient construction hereinafter described, andparticularly defined in the.

' claim appended.

In the accompanying drawings, forming part of this specification, Figure1 is a view illustrating parts of a door-casing and a swinging door andmy improvements properly arranged relative to the casing and door. Fig.2 is a horizontal section taken in the plane indicated by the line 2 2of Fig. 1 looking downwardly, and Fig. 3 is a detail vertical sectiontaken in the plane indicated by the line 3 3 of Fig. 1.

Similar letters designate corresponding arts in all of the views of thedrawings, reerring to which A is a door-casing of the ordinary or anyother suitable construction.

B is a swinging door, preferably a screendoor, hinged at a, to casing A.

C is the horizontal rotary fan of my improvements, and Dis the uprightrotary fan thereof. v

As best shown in Fig. 1, the fan 0 comprises a shaft 1), journaled inbrackets c, d, and e, fixed on the outer face of the upper bar of casingA, a blade 3, of galvanized sheet-iron or other suitable material, fixedwith respect to and carried by the shaft, said blade extendinglongitudinally of the shaft from thebracket d to a point adjacent to thebracket e, and a drum E, preferably of wood,

' arranged on the shaft 6. The said drum E is provided in its inner endwith a kerf h, Fig. 2, which receives the end of the blade f, whereby itwill be seen that the blade is utilized to strongly hold the drumagainst turning with respect to the shaft 6 and the said blade, and thiswithout the employment of extraneous devices. At its endremote from theblade f the drum E is provided with a metallic cap 9, the purpose ofwhich is to prevent frictional Wear of the drum against the bracket 6.

The upright rotary fan D ismade up of a shaft m, journaled in lower andupper brackets n p on the outer face of the casing-stile fan adjacent tothe swinging edge of door B; a blade 1", of galvanized sheet-iron orother suitable material, carried by the'shaft m; a ped, estal 8,preferably of wood, having a kerf in its upper end receiving the lowerend of the blade 1" and also having a metallic cap t on its lower endadapted to prevent frictional wear of said lower end against the bracket7, and a drum M, preferably of wood, arranged on the shaft m and havinga kerf a, Fig. 3, in its lower end receiving the upper end of the blade1', whereby it is strongly connected of itself to said blade, so as toturn therewith and transmit rotary motion thereto, as presentlyexplained. On its upper end the drum M of fan D is provided with ametallic cap as, designed to revent frictional wear of said end againsttile bracket 1).

T-is a coiled spring arranged on the shaft of the fan 0 between thebrackets c and d and connected at one end toone bracket and at itsopposite end to the shaft,

U is a guide-pulley attached to the doorca'sing at the right of the drumM, V a guidepulley attached to the door-casing at the left of the drumM, and W a cable connected to and wound on the drum E of fan 0, passedthrough the guide-pulley V in front of the drum M of fan D, through theguid'e-pulleyU and back of the drum M, and connected to the door B. Invirtue of this construction it will be observed that when the door B isopened the cable W will be drawn off the drum E of fan 0, with theresult that the fan 0 will be rotated and the spring T placed undertension. It will also be observed that incident to the opening of thedoor the stretch.

of cable intermediate the guide-pulley U and the door will by bearingagainst the drum M rapidly rotate the vertical fan D. When the door,having been opened to the extent desired, is released, the spring T willrotate the C in the direction-opposite to that first mentioned and by sodoing will wind the cable on the drum E, rotate the fan D, and return toassist in returning the door to its closed position.

The rapid rotation of the fans above and at one side of the doorincident to 0 closing of the door willobvious y frighten flies and deterthe same from entering an apartment through the doorway.

It will be gathered from the foregoing that my improvements are adaptedto be applied to an ordinary door-casing and door without ening andinvolving change in the structure thereof and fvligzhout the necessityof employing skilled a or.

Having fully described my invention, What desire to secure as claims byLetters Patent is- The combination of a door-casing, a swinging door,rotary fans mounted on the casing above and at one side of the door andeach comprising a shaft, a blade carried by and fixed to each shaft, anda drum arranged on each shaft and having a kerf in its inner endreceiving one end of the blade, whereby the drum is fixed to the shaftby the blade, a spring for rotating the fan above the ,door in 15 onedirection, and a cable connected to the drum of the said fan and theswinging door and engaging the drum of the fan at the side of the door.

In testimony whereof I affix my signature 20 in presence of tWoWitnesses.

PHILIP F. HODGES.
